A process for the generation of dried cellulose and cellulosic material as well as ready-to-use cellulose products prepared by this process

摘要

The task was to dry cellulose and cellulosic materials with the least possible time and technical and economic effort without destroying the cellulose and without loss of stability and effectiveness of any additive substances, for example pharmaceuticals, and, if necessary, to almost completely re-source the original structure and consistency , According to the invention, the dried cellulose or the cellulosic material to be presented is exposed to the adsorbing influence of a moisture binder, in particular an osmotically and / or hygroscopically active solution, for the purpose of drying with preservation of the swellability with almost complete recoverability of the cellulose structure and consistency, and thereafter irrespective of a structural change of the material dried.
